And the description of those who disbelieve and the one who calls them to guidance and faith is like the description of the shepherd who shouts at the cattle and rebukes them, while they do not understand the meanings of his speech, but only hear the call and the echo of the sound. These disbelievers are deaf, having blocked their hearing from the truth, dumb, having silenced their tongues from speaking it, blind, their eyes not seeing its dazzling proofs, so they do not use their intellects in what benefits them.
